I just installed this playground. It is very nice and full of great features for kids. However my 
great concern is about your advice to put 9 inches of loose material around this playground. I have to tell you that there is no way of having more than 3 inches of loose material around your playground. It is designed to stand on the surface, preferably grass. I wish I did that instead of the sand. I have to now remove about 20 tons of sand, as 9 inches around the playground makes it unusable. It's way too deep, the swings are almost sitting on the sand. I wish you were more honest in your instruction booklet and properly advise customers of what the intended surface is.
